Neon — A Liquid Prompt Theme

Neon is a theme for Liquid Prompt.

It is based on the default theme but on three lines and with a more pronounced color scheme.

If you are running some command in a Git repository:

When Liquid Prompt is displaying a lot of things, it may look like this:

Rationale

The neon theme is an extension of the default theme, featuring a "techno-ascii-art" style.

This prompt is a fully usable theme, designed to be easier to visually parse than the default theme.

It is also an example of how to build a theme modifiyng colors and structure of the sections.

The theme features three rows:

1. the first one hosting "secondary" information, in blue (jobs, sensors, dev context, etc.),
2. the second row displays "primary" information (user, path, VCS, etc.), in green,
3. the third one is dedicated to the prompt (runtime, error code, prompt mark), in cyan.

Within each row, important notice are displayed in bold (and thus probably in a slightly lighter color, depending on your terminal configuration).

Install

Just download this repository somewhere, source the theme file and activate the theme from your shell configuration file.

For example (just use ~/.zshrc instead of ~/.bashrc, if you use Zsh and not Bash):

git clone https://github.com/nojhan/lp-neon.git
echo '# Use Liquid Prompt only if in an interactive shell
    if [[ $- == *i* ]]; then
        # Use Liquid Prompt
        source ~/.liquidprompt
        # Use the Neon theme if it has been downloaded in ~.
        if [[ -f ~/lp-neon/neon.theme ]] ; then
            source ~/lp-neon/neon.theme && lp_theme neon
        fi
    fi' >> ~/.bashrc

WARNING: Normally with Liquid Prompt's themes, you may source several themes, switch between them and get back at the previous one. However, with Neon, this may not work properly, because it abuses the Default theme's configuration.

Configuration
